A mixed strategy for efficient acousto-electric tomography based on complete electrode model

Abstract : In acousto-electric tomography (AET), the electrical conductivity distribution in a domain of interest (DOI) is constructed from power density data measured under the disturbance of focused ultrasonic wave. However, the power density cannot be measured directly. One needs to reconstruct it from the potential on the full boundary of DOI, which is not practical to measure. A new reconstruction strategy is proposed herein. The boundary potential is firstly reconstructed with electrical impedance tomography algorithm based on a complete electrode model (CEM). The power density is then reconstructed from the boundary potential for reconstr
